Voyer Millésime 1993 may be really good - too many good signs about it. Price seems to be quite high for its age (170-180), but if it's that good maybe it's justified.
I mean, I'm not sure if there are two different bottlings, because I haven't found a single photo with 56,3% on the internet. Still, 2023 53,6% should be at least ok. ;)
